Toss in the wash with cold water. Air dry. Boom.
Cute but different quality?
"These flats are so cute. I have two other older pairs of the point and I love them, however, I have worn these a few times and have some blisters on my heels from a break in period. I have never had a break in period with any of my Rothy’s before and definitely never gotten blisters before. The shoes are still cute, but not sure if the quality has dropped from previous versions."
